Australia is home to some of the world's deadliest animals. However, few are as dangerous as the cane toad. Native to Central and South America, the innocent looking amphibian is an invasive species that was imported to Australia in 1935 to control the native grey-backed cane beetles that were harming sugarcane crops. With very few natural predators their population began to grow rapidly. Experts estimate that there are currently over 200 million specimens spread across Northern Australia, and the numbers are only growing.

noridog9년 이상The toad is really ugly- shani9년 이상This is when researchers started to take action. After some tries to curb the toad's population growth didn’t succeed, a group of researchers led by Georgia Ward-Fear, came up with a plan. They decided to train them to avoid the toads! To test the idea they went to a floodplain in the Kimberley region of northwestern Australia that had no population of toads there. The smaller animals give off the same toxin as adults but in smaller amounts. While the poison does make the reptiles sick, it does not kill them. The researchers say it took a couple times to teach the lizards to avoid cane toads altogether. Researchers published their study in the Biology Letters journal on January 6, say putting small frogs in places that have not been invaded by toads can help curb the decrease of the lizards.
